If you ever need to take a sleeping type pill, well Ambien is your choice, trust me. I'm going through a rough time right now and my doctor said I should take Ambien about 30ms. before I go to bed. If you use this drug... KNOW WHEN YOU WANT TO GO TO SLEEP! This thing kicks in FAST!!! It's half life is short, very short. It's out of you when you wake up. I've been using this. And I took the med about 30mins. ago and my head is falling into my iBook. Just a recommendation.
